Hi Andrei,

You are using Linux.

The Close class has been added in the latest version of the svg.path package.
It seems that the repositories are not up-to-date.
Try to install it like this:

sudo pip3 install -U https://github.com/regebro/svg.path/archive/master.zip

There are other people who reported this and they did solved it like this.

I’ve modified the requirements.txt file to reflect the need of at least version 4.0

From the Release Notes of svg.path package:

4.0 (2019-11-02)----------------
- Moved all the information from setup.py into setup.cfg.
- Added a Close() command which is different from a Line() command in  no way at all, to simplify the handling of closepath commands and subpaths.
- Path()'s no longer have a `closed` attribute.
- Now fully supports the SVG 1.1 "F.6.2 Out-of-range parameters" list.
- Uses circular maths to calculate the length of circular arcs,  more accurate and much faster.

FlatCAM beta needs the dependency package svg.path with the version at least 4.0. I've updated the requirements.txt file to reflect this necessity.
